Specification of Joe latented July 9, 199?.

My invention consists first, in a circuit controller 7 comprising a rotatable trailer and an inclosing casing within whichthe trailer is mount d, the said casing having bearings uponboth sides of said trailer, second, in certain details of construction and novel combination of parts, as will hereinafter be more fully set forth; and third, in an improved construction havi more than one series of contact points, the respect tact points of the several ser connected.

The objects of my invention are to improve zrjflil simplify circuit controllers employed-for tire purpose described; to provide such an extent and. lot-stun oi bearing surface as to prevent the parts from oe -coming worn, with the result that the" parts would hecon e loose, and poor contact be made, as has been common being also in the past; to entirely inclose the trailer within a practically dirt-proof chamber, so as to prevent dirt from working in and clogging up the parts; and to pro- .vide a simple and compact arrangement whe circuit controller may be run at a relatively s10" I will now describe an embodiment ther ring to the-accompanying drawings to illust same, and will then point out the novelieatures in claims.

In the drswingsFigure 1 is a view in central trans" e conmounted. upon the said bushing l. the said casing inclosing a chamber 9 containing the trailer. 6. The casing comprises two disks 10 of electrically nonconductive material, arranged upon opposite sides of the trailer 5, two flanges 11 11 adjacent the outer faces oi the said disks, and having a bearing upon the bushing t, and a ring 12 of electrically non-conductive material, arranged between the two disks 10, 1O. Bolts 13 serve to secure the disks 10, flanges 11 and ring 12 together.

One of the flanges 1.1 is provided with an arm 1-1, by which the c mug 8 may be manipulated, it being understood that the casing is ordinarily held stationary, while the trailer-and shaft upon which it is mounted revo vo; the casing, however, being permitted limited rotative movements in either direction, through movements given to the operating arm 14, so as to relatively advance or retard the position thereof with respect to a revolution of the shalt 3.

The ring 12 suppoi it a plurality of contact points 15 The contact points 15 and 16 are precisely alike, but comprise two series, the points of one series being elect ally connected respectively with :oi-respomling points of the other series. The wires which connect the opposite contact points are preferably located in grooves 17 arranged between the outer faces of the ring 12 and the inn faces oi the disk 1.0, such wires being perie t y insulated by the factthat both the disks 10: and 12 ol insulating material.

is .ircuit controller herein is shown with eight contact points in for each series. The usual circuit controller for a iour lindcr engine of the four-cycle type has i s contact points, and is arranged with a 2 to 1 mntrollcr revolves once for every he main shaft revolves." Such an arrangeg in each cylinder, once in every other a- ,ooin l one half of a revolution ahead ol the spark in another cyliu dcr, 11., a spark at every half revolution in the various cylinders progressively.

My present circuit controller is similarly arranged for of the four-cycle type, but it is' uaclpoints, of which the oppo site contact points an e "tic-ally connected together, either one of such oppositely arranged contact points being thus adapted to produce a spaa in the same cylinder. This arrangement is illustrated in Fig, 3 of the drawin s, the spark plugs 21 of the engine 22 l ning shown as electrically connected in multiple with oppr site contact points of the circuit controller. "he circuit controller may then be connected with the drive shaft oi the engine at a ratio of l to 1, ins cad of 2 to 1,

18 and 3, having speed or ratio of 4 to 1.

The number of the contactpoints will be. of course. varied in accordance with the number of cylinders and classof engine provided, and while I have shown two series of contact points employed. a greater number of series may be employed if desired. the speed ratio oi" thetcircuit controller being iroperly proportioned, will be readily understood.

The construction of the circuit controllerwith more than one set of contact points and with the individual contact points of one set in electrical connection with corresponding points of another :set by means of wires contained in the grooves 17, results in an extremely simple and compact device in which there is practicallv no liability of cross contacts lit-inf: made through dct'et'tivc insulation and the danger of the connectiousiu ('Hlllllil broken is reduced to a lllllllllllllll.

What I claim is:

1. A circuit controller conn'irising a bushing having a trailer connected thereto. two electrically non-conductive disks upon said bushing. one on each side of said trailer. two flanges arranged outside of the said disks and each having a hearing upon the bushing, a contact hearing ring between the said disksand means securing disks. flanges and ring together.

2, A circuit controller comprising; a bushinghaving a trailer connected thereto, two electrically non-eonductive disks upon-said Bushing, one on 'each side of said trailer, two flanges arranged outside of the said disks and each having abearing upon the bushing, a ring, between the said disks, said ring comprising an annulus of electrically nonconductive material and contact points carried thereby, wires connecting certain of said contact points together, located in grooves between said disks and said ring, and means securing disks, flanges and ring together.
